Oneness Pentacostalism comes to mind, although it was born more out of a “revival meeting”
I often see opposing views to Orthodox Christianity, coming from a personal revelation one received, while studying the Scriptures
Im not much for lifting things from wikipedia, but for the sake of expediency, Eh :shrug:
In April 1913, at the World-Wide Apostolic Camp Meeting held in Arroyo Seco, California and conducted by Maria Woodworth-Etter, organizers promised that God would "deal with them, giving them a unity and power that we have not yet known." Canadian R. E. McAlister preached a message about water baptism just prior to a baptismal service that was about to be conducted. His message defended the “single immersion” method and preached “that apostolic baptism was administered as a single immersion in a single name, Jesus Christ,” saying: “The words Father, Son, and Holy Ghost were never used in Christian baptism”. This immediately caused controversy when Frank Denny, a Pentecostal missionary to China, jumped on the platform and tried to censor McAlister. Oneness Pentecostals mark this occasion as the initial “spark” in the Oneness revival movement.
**John G. Schaepe, a young minister, was so moved by McAlister’s revelation that, after praying and reading the Bible all night, he ran through the camp the following morning shouting that he’d received a “revelation” on baptism, that the “name” of the Father, Son, and Holy Spirit was “Lord Jesus Christ”. **Schaepe (whose name is often misspelled Scheppe in a number of sources) claimed during this camp-meeting that the name of the Father, Son, and Holy Ghost was the name Lord Jesus Christ which name was later part of the baptismal command posited by Peter in Acts 2:38 — i.e., baptism “in the name of Jesus Christ” — was the fulfillment and counterpart of the Great Commission in Matthew 28:19 constituting baptism “in the name (singular) of the Father and of the Son and of the Holy Spirit (which “name” Oneness believers hold to be that of Jesus).” This conclusion was accepted by several others in the camp and given further theological development by a minister named Frank J. Ewart.
On April 15, 1914, Frank Ewart and Glenn Cook publicly baptized each other in “the name of the Lord Jesus Christ, but as the one name of Jesus, not as a Trinitarian formula.” This is considered to be the historical point when Oneness Pentecostalism emerged as a distinct movement.
